hi all,
I want to enable dma for devices, but i can't. i used hdparm and it is giving the following error....
plz helpCode:hdparm -d1 /dev/hdb
/dev/hdb:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
how could i enable this...
what could be wrong
i am using knoppix 4.02 version
thanks in advance
viji
Try:
sudo hdparm -d1 /deb/hdb
The "sudo" command lets you run a command using the Superuser authority, otherwise known in Unix/Linux as the "root" user account.
To open a terminal window with superuser authority, you can type:
sudo su
and you can even create a "root" account password with:
sudo passwd
i issued the command as a super user, but also the same error
plz help
are you sure ?
why the hdb ?
do you have a hdb ?
most systems have an hda
mine works with
-d1 and
-d 1
what is there if it is hda or hdb
my harddisk is connected as primary slave that's why hdb...
anyway in my case its not working....
